基于ANSYS的机械密封环开槽对比分析

Comparative Analysis of Sealing Ring Slot Machines Based on ANSYS

摘要: 为分析机械密封环开槽对机械密封性能的影响，通过对机械密封环的结合面不开槽、以及分别在静环和静环座开槽三种情况进行有限元分析，查看运转工况下的应力场、结合面接触压力、密封端面轴向变形、温度场分布。根据对密封性能的影响，确定合理的开槽情况。通过分析发现，开槽比不开槽的密封性能好，在静环座开槽的密封性能最好。

Abstract: In order to analyse the effect of making slots on sealing performance of mechanical seals, according to three finite element analysis, including no slotting in mechanical sealing ring of interference fit face, making slots in stationary ring and stationary ring base, the operation conditions of stress field, contact pressure of interference fit surface, the end face axial deformation, temperature dis-tribution are drawn. Based on the effect on sealing performance, a reasonable slot situation is de-termined. Through the analysis it is found that slotting is better than no slotting over the sealing performance; making slots in stationary ring base has the best sealing performance.
